Yes, of course my machines have names....
My vintage Singer 66 hand-crank is named Ambrozina, after my grandmother.
My hale-and-hearty little Kenmore, who does anything I tell her to and gives me no problems, is named Edna. That just sounded like a "sturdy" name to me.
My (new, not antique) Featherweight 75 is called Tinkerbell, because she's my lightest machine.
My PITA Singer Quantum L-500 machine is named Paris Hilton, because she's a high-maintenance, fussy little twerp that only sews when she feels like it. But don't get me started on that subject....
